I'm shrunk down to 5' 6" and ride a Hyper beach cruiser with 26" wheels with no problem, you got 5 inches on me...lol.I’m 5’11. The bike is a Raleigh 26 inch
I also owned a classic Raleigh 26 inch 3 speed pedal bike that I bought back in the 1980s that I also had no problem reaching the pavement with my feet...lol.
I see you have your set raised, try lowering your seat to fit you on it properly...lol.
